Be it known, that L JnMEs M. HARRISON, of Rochester,- inthe county of. Monroe and State of New York, have inventedcertain new and .usefullmprovements in Thread-Twisting Ma-` chines; and I doy hereby declare the following to be a full, clear, andy exact description of the same, reference being had to the accompany# ,ingrdrawirigal -forminga part of this specifi- IO cation, and to the'refereneefvnumerals 'marked thereon. y.. n v,

lThe lobject of mypresent invention is to ffacilitate the operation of twisting yarns,`

threads, cords,Y and the like by performing vI 5 Asuch anoperationbymeansof an implement especially adapted for the purpose instead of that may be manipulatedvwith convenience 2o and which'will run rapidly and smoothly in operation. K A

To these andfother ends, my invention consists certain features `of construction and arrangement to be hereinafter explained, the

2 5 novel features being'pointed yout in the claims hereunto annexed. i v

In the accompanying drawings, Figure 1 is side elevation of a device embodying, my in- Vention, partsbeing insection; and Fig. 2 is 3o a top .plan View ofthe same, 1n order that a more complete understand- .ing may be hadofv my invention, reference will be had to the herein-shown embodiment thereof, wherein 1 designates the supporting- 3 5 frame of the machine, having an upwardly-l extending and forwardly-curved arm 2, carrying at its upper end a horizontally-disposedy `bearing 3 and directly beneath it` the vertically-disposed bearing 4, the latter being arranged in alinement with the bearing 5, care ried by the forwardly-extending arm 6 of the base of the frame. Journaled in the bearing 3 is the shaft 7 carrying at one end the driving-wheel 8 and at the opposite end the adjustable stop-collar 9, against which bears the helical spring, 10 in such a manner as to exert a force tending to separate the collar and the washer 11, that is loosely mounted upon the Serial No. 129,066. (Nomodel.)

i 'shaft Tandarrangedto bear against the end of the bearing 3, the effect of .this separating action between said collar andwasher tending to hold the 'driving-wheel'against its driven Wheel with a'yielding pressure. The driving-` wheel 8 is provided with an Operating-handle 12, .by means of which it may be rotated, and in an annular groove upon the periphery of this 1 driving-wheel is fitted an linset friction-band 13, bearing. under thel action of the spring 1Q upon thesurface of the friction`wheel`14, mounted upon the' shaft15, journaled in the bearings 4 5, the relative dimensions of the wheels 8 andv 14 being preferably such that Mounted upon the shaft 15 and rotating in the grooved periphery ofv which runs the `belt 17, passing aroundv the pulley 18 o f comparatively smaller diameter and mounted fastupon the s'pindle19, which latter is revolubly mounted in thefspindle-support 20, and into belt, the spindle-support 20'is slidinglymountthe speed of rotation of the latter will be materi'ally' increased over that of the former. byhand, as heretofore practiced; and it con-A l 65 .sists in producing. a devi'ce of thischaracter i with the friction-wheel 14 is a belt-wheel 16, i

f the upper end of this spindle is removably i ed in the slot 23, formed in the base ofthe Ina-v spondingprojecting portion upon the adjust-- able bearing to insure a firm and proper seating of the pulley 18 in relation to the pulley 1 6 at Various adjustments of the bearing.

In manipulating amachine of the character above described the thread to be twisted may be doubled upon itself or otherwise folded, as desired, and attached to the hook of the spin- -dle, while its free ends are held in one hand of the operator, and with the other hand the driving-wheel is operated until the thread has been twisted to the desired degree, at which time the thread may be waxed or otherwise treated and finally removed from the hook to be subsequently used for any desired purpose.

Such a deviceA constructed in accordance with my invention is comparatively simple and inexpensive to manufacture, and when employed for the purpose above described it may be operated with the utmost facility and convenience, as the axis of the revolving spindle extends in a line substantially parallel to the plane of rotation of the drivingwheel, thereby enabling the latter to be operated by one hand of the operator while the other holds the thread extended in a direction substantially in line with the axis of -rotation of the spindle. Such a device will also run smoothly and noiselessly in operation, and as the embodiment herein described is very compact and provided with an improved driving mechanism that is especially adapted to a device of this character it will be seen that a thread-twisting device is produced that renders it possible to simplify and facilitate the operation above described and to enable the operation to be completed in a small fraction of the time required in twisting the thread by hand.

I claim as my invention- 1. A thread-twisting devicecomprising a frame having a slot therein, and a bearing slidinglyiitted in said slot,havingarevoluble spinelle mounted therein, a thread-engaging hook having its shank axially centered in said spindle and removably held therein, an arm carried by said frame having a driving-wheel mounted thereon, and intermediate driving wheels mounted between the arm and frame and a belt connecting the intermediate wheels to the spindle for operating it.

2. A thread-twisting device comprising a frame having an arm carried thereby, a driving-wheel mounted on said arm and in frictional engagement with intermediate driving mechanism embodying a wheel of smaller diameter upon said frame,means for holding said wheel and a belt-wheel rotating with said smaller wheel, a spindle-bearing mounted on said frame carrying a revoluble spindle provided with a pulley, a belt adapted to connect said belt-wheel and spindle-pulley, means for adjusting the relation between said spindlepulley and belt-wheel, and a thread-engaging hook carried by said spindle.

3. A thread-twisting machine comprising a frame having a slot formed therein provided with an undercut portion at one side thereo'f, of a spindle-bearing slidingly iitted in said slot and having a projecting portion entering the undercut portion of the slot, and means for retaining said bearing in adjusted position, a spindle revolubly mounted in said bearing, a thread-engaging hook carried by the spindle, a driving-wheel mounted on the frame and arranged to rotate in a plane substantially parallel to the axis of rotation of the hook, and intermediate devices driven by the drivingwheel and connected to the spindle by a belt so arranged as to be tightened by the adjustment of the spindle-bearing.

4. A device of the character described comprising a base, a spindle revolubly mounted thereon and carrying a hook to engage the thread to be twisted, a belt-wheel revolubly mounted on the base, a pulley of smaller diameter on the spindle connected to the beltwheel, a friction-wheel connected to and revolving with the belt-wheel, and a drivingwheel provided with an operating-handle and having a friction-band in the periphery thereof arranged to bear-upon said friction-wheel, a shaft upon which the driving-wheel is mounted, a stop-collar carried by said shaft, and a spring interposed between said collar and a relatively stationary portion of the base, and arranged to maintain said driving-wheel in frietional engagement with the friction-wheel.
